' Application filed April 1, 1922. SerialNo. 548,698.

Be it known thatI, JAMES F. BAILEY, a citizen ofthey United States,residing at Columbia, in the "county of Richland :t and State of SouthCarolina, haveinvented certain' "new "and useful Improvements inWrenches 1 andll do hereby declare the following'to be a full, clear,and exact description of the" invention," such as will enable othersskilledin the artto which it appertains' to make and u'sethe same.

This inventionrelates to a tool of the wrench type embodying a handleand inner and: outer j aws, .the inner jaw being slidable along'thehandle and held inthe required adjusted position primary object of theinvention is the provision of a wrench of the .type aforesaid embodyingan improved form of handle and j awstructure and arrangement, wherebythe tool maybe cheaply manufactured and assembled and islcapableof beingeffectively used either a'nut or pipe wrench, and which may .have bothjaws fixed but relatively 'adjustable, or which may have one ofthelja'ws relatively fixed and the other pivoted, according' toj thespecific formation of the tool. j

Other'o-b jects and'a'dvantages will be apparent and suggestthemselvesas the nature of theinvention is understood.

While the drawings illustratean embodiment of the inventionitjis to'beunderstood.

that in adapting the same to meet different conditions and requirements,various changes in the form,proportio n and minor details ofconstruction 'may be resorted to without departing from the nature ofthe. invention. "Referring to thelacco" panying. drawings formingapartof the application, Figure 1 is a side-view-of a wrench embodyingthe invention, j Figure 2 is a view sim'ilar'to Figure 1, the handlesection .on the near side being removed, j v Figure 3 is a rear edgeview of the wrench,

Figure 6 is a side view of a modification, Figure 7 is a rear edge viewthereof, Figure ,8 is a detail view of the outer end portion of thehandle with the near section removed and the outer jaw in section,

. Figure 9 is a detail viewof the inner jaw anda portion of the shank towhich the jaw is ivoted, k

Figure 10 is a detail longitudinal section. on-the line '1010 of Figure6,

Figure 11 is a detail section on the line l1'11"of Figure 6, and "Figure12 is a detail view of the. facing or grip for the inner pivoted jaw.

Corresponding and like parts are referred toin" thefo-llowingdescription and designated in'the several 'views of thedrawings by like reference characters. i The wrench comprises a handleand an outer and an inner jaw, the latter being slidable along thelength of the handle. The handle is of sectionalformation, the sectionsbeing of similar or like formation and each section comprising a bar 1and a semi-cylindrical portion 2,-the latter having an inner rib 3 atits outer end which constitutes an element of'the swivel connectionbetween the handle and the adjusting nut by means of which the inner jawis moved. When the sections ofthe handle are assembled, the bar portions1 are spaced'apart andextend in parallel relation, whereas thesemi-cylindrical portions 2 come together and are secured in any manner,either by fastening-s ior by being welded. The fastenings 4 may consistof rivets, bolts or machine screws. The outer jaw 5 is fixed andcomprises similar sections which are formed with the respective sectionsof the handle. A tongue and groove joint is formed between the sectionscomprising the jaw 5 to insure the strain on the jaw when the tool is inoperation being uniformly sus tained by both sections. The tongue isdesignated by the numeral 6 and the groove by, the numeral 7 and theseelements match when the sections of the jaw are assembled. Fastenings,8, such as rivets, machinescrews orbolts, connect the sections of the.j awwhen the parts are placed together. I

The inner jaw 9 isslidable lengthwise of the handle towards and awayfrom the outer fixed jaw. The jaw 9 has a shank 10 which is slidablebetween the bars l and into the cylindrical portion 1 of the handle. Athreaded stem 11, forming a part of the shank 10, cooperates with a nut12 which is disposed within the cylindrical portion of the handle andhas a swivel joint connection upon its outer side to enable the hand toobtain a firm grip thereon whenrotating the nut 12 to adjust the jaw 9.Theinner'or head portion of the jaw 9 receives the bar portions 1 of thehandle, whereby the jaw .is'braced so as to withstand-the strain .to

which it is subjected when the tool is in operation. The jaws 5 and 9are relatively fixed, thatis, they have no pivotal movement, the outerjaw 5 being immovable and the inner jaw 9 adjustable. v

In the modification shown in Figure 6 and the detail views thereof, thegeneral construction and arrangement of theltool corresponds with thatherein before described, corresponding parts being designated by likereference characters The main difference resides in the innerjaw and itsmounting, the same being pivoted and both jaws being disposed at a rightangle to the length of the handle,,wh-ereas the corresponding aws in theformshown in Figure 1 are inclined to the handle.

The inner pivoted jaw 15 of the modificationisformed with a tongue 16which is pivoted tothe shank 10, the forward end of which is cut away toreceive the tongue 16. A pivot 17 passes through the over- Y lappingparts and pivotally connects them.

A spring 18 is interposed between the forward portion of the jaw 15 andthe handle 1 and serves to hold the gripping jaw 15 pressed outwardly togrip a pipe or like article and enable said jaw to ratchet whenoscillating the wrench to turn the' pipe or other work gripped betweenthe two jaWs.

. The r'ecesses'19 formed in they sides of the jaw 15 are forwardlywidenedto admit of i I the jjaw'having a limited pivotal'movement whenthe tool is in operation. jaws has a facing or grip section 20 detach.

I ably fitted thereto and formed of high grade which is essential toadmit of its ratcheting Each of the steel to maintain the bitingedges ofthe teeth formed thereon. The facing or sections 20 may be attached tothejaws in any preferred way whereby they may be removed when required.i

What is claimed is z I 1. A wrench comprisinga handle'having a jaw atits outerend and comprising similar sections, each including a bar and asemi-cylindrical portion, an inner'jaw slidable between the bars of thehandle, and

means located within the cylindrical portion of the handle for adjustingthe inner jaw towards and away from the outer jaw.

2. A wrench comprising a handle consisting of similar sections; eachincluding a bar and a semi-cylindrical portion, a fixed jaw at the outerend of the handle comprising complemental section's formed withtherespective bars of the handle, an inner jaw i slidable between thebars comprisin .the

handle, and means within the cylinc rical portion of the handle foradjusting the inner jaw towards and away from the outer aw.

ing similar sections,'each section including a bar, a semi-cylindricalportion andaijaw portion,-=the jaw and semicylindrical portions of thebars coming together and the remainder being spaced apart, a shank.between the handle sections, a jaw "pivotally mounted vupon the outerend of the shank, a'spring carried by and normally :eierting 3.
